gfe-relnote: Send IETF QUIC, HTTP/3 and QPACK error codes in CONNECTION_CLOSE frames.  Protected by gfe2_reloadable_flag_quic_enable_version_draft_25_v3 and gfe2_reloadable_flag_quic_enable_version_draft_27.

Map each QuicErrorCode to an appropriate IETF error code.  QuicErrorCodes that
are never used, or not used with CONNECTION_CLOSE frames (only internally or
only with GOAWAY frames) are mapped to INTERNAL_ERROR.  Add test to enforce that
mapped error codes are valid transport or application error codes.
